Worked Solution & Example Answer:Details of a disassembled Bird Feeder are shown in Fig - Leaving Cert DCG - Question C-5 - 2011
Step 1
Draw a full size sectional elevation on A-A showing the parts fully assembled with the lid closed.
Answer
-
Outline the Base: Start by drawing the shape of the base as per the dimensions provided in the figure. Ensure to depict any recesses and holes as indicated.
-
Add Seed Holder and Hinge Pin: Position the seed holder correctly on the base and include the hinge pin. The outline should clearly show the relationship between these components.
-
Include Perches: Draw the perches as specified, ensuring correct outlines, hole placements, and pin details.
-
Draw the Lid: Create an accurate representation of the lid, noting the arc and its center location. Make sure the top edge is defined correctly to understand its arc of motion.
-
Draw Fillets and Chamfers: Add fillets of 6mm and chamfers of 1.5mm wherever applicable to give a realistic portrayal of the parts.
-
Final Touches: Ensure all components are relative to each other in their positions, adding any necessary hatchings and centerlines for clarity.
Step 2
Step 3
Lines from center and indication of angle.
Answer
From the center of the hinge, draw lines representing the limits of the lid’s movement—one showing the closed position and another showing the fully opened position. Indicate the angle between these two lines to illustrate the rotation visually.
